BED-SPRING.y

Specification of Letters Patent. Y Patented May 11, 1915.

Application filed November 4, 1912. Sera1No'f29A78.

Beit known that we, GEORGE F. SisBowER, a citizen ofthe United States, residing at East Orange, in the county of Essex and State of New, Jersey, and Louis EDWARD PITTONI, a subject of the -King of Italy, re-

f siding at New York city, county and State 4to the fabric. our arrangement, 1s secured directly to a of New York, have invented certain new and useful Improvements in Bed-Springs,

the following being a full, clear,and exact disclosure of the one form of our invention which weat present deem preferable.

For a detailed description of the present form of our invention, reference may be had to the following specification and to the accompanying drawing forming a part thereof, in which- Figure 1- is a plan view partly in section of a portion of a bed-spring fabric provided with our improvement. Fig. 2 is a vertical section through the edge of the fabric. Figs. 3, i and 5 show modifications.-

Our invention relates to bed springs of the type formed by a metallic mattress fabric adapted to be stretched under spring tension Ona rigid frame.. It involves a device for reinforcing the edge of the fabric and securing it to the end springs which ordinarily intervene between the 'fabric and the frame on which it is stretched. i

Referring to the drawing,A represents the metallic fabric, preferably what is known as a woven wire fabric, and B represents one side of the frame on which the fabric is to be stretched. Between the fabric A and the framebar B are series of coiled springs C, C, etc., such as'are ordinarily interposed at that pointto give resiliency to the structure, one end ofeach spring being hooked into the frame-bar. and the other end secured The' edge Of the fabric, in

metallic piece D which we term a core piece or core bar, the fabric being preferably fold* ed around it. The said corepiece is shown in Figs. l and 2 in the form of a metal rod or bar with extensions F, F, etc. thereon at-v intervals. These extensions project .away

from the edge of the fabric toward the frame-bar B and are perforated for receiving the end-springs C, C `whichare hooked into the perfor-ations. In Fig. 5 the core piece D is inthe form of a round rod'or wirewith the extensions F produced by bending thereon under heavy pressure.

nal space within the cover plate is largerv the rod or wire into loops. In Figs. 3 and. 4f the core piece D is in the form of a'plain fiat bar without the extensions but perforated at intervals for there'ceptionvof the end springs which eng-age it. The fabric itself is also perforated correspondingly, by

the pushing aside of the wires of which it is woven, so that the extensions F may ro- ]ect through the fabric, or the hooksfof the end springs may pass through the fabric when the core piece is .of the form shown in Fig-s. 3 and 4. Outside o f the core piece D 1s' placed a metallic U-shaped cover plate E1 which bis also perforated at intervals to re ceivieqthe extensions F or the hooks' of the end springs, in the form shown in Figs 3 and 4; *This cover plate embraces between its upper and lower portions the core piece and also the edge ofthe fabric, being bent down where it embraces the core piece and fabric, and is smaller outside the core piece where it merely embraces and pinches down on the fabric itself. Bv this means the cover plate is'secured in place by virtue of its grip on Athe core piece, vwhile by having the folded edge of the fabric gripped or pinched in the smaller portion of the internal space within the cover plate the fabric is more securely held against detachment from the core piece.

AAmong the advantages of our arrangement is the fact that it is far cheaper to constructl than the one now 'commonly employed, wherein separate metallic strips are riveted above and below the edge ofthe fab; ric, besides which, it -gives a more attractive and neater finish to the fabric and provides "and retained by 'the cover-plate, the said Vcore piece being adapted for the engagement of spring-hooks therewith and the cover-plate being perforated at intervals to permit such engagement of the hooks and core-piece,

The interpressed int'o engagement with the fabric at one side of the core to grip and retain in place the folded fabric.

.4. A Woven-Wire mattress-fabric havingits edge inclosed by a cover-plate independent'of the end rail of the frame and bent into a horizontal U-shape, a core-piece adapted to be engaged by the attaching spring hooks and having the fabric bent over it and retained by the cover-plate being pressed into engagement with the fabric at one side of the core,v and the said cover.

plate being perforated at intervals to per-k mit of the said engagement of the core-piece and hooks.

5. 'A- Woven-wire mattress-fabric having its edge inclosed by a cover-plate secured thereto independentlyf the end rail of the mattress frame-andperforated at intervals, a core-piece Within said cover-plate over Which 'the edge of the fabric is turned and loops or eyes projecting through said perfo- I rations in the cover-plate.

6. A-Woven-Wiremattress-fabric having-a folded plate inclosing the edge of the mattress, anda retaining core-piece also i-nclosed by said plate and provided with a series of loops or eyes projectingl through a corresponding series of openingsjjginl the plate.

7. A Woven-Wire mattress-fabric having a folded plate independent of the mattressframe inclosing the edge of the mattress, and a retaining core-piece also inclosed by said plate, the core-piece and the plate both having a series of corresponding per-forav tions and the core-'piece being secured tothe fabric by the grip of the said plate thereon.

8. A Woven-Wire mattress-fabric having'a fiat folded plate independent of the mattress frame, and a retaining core-plate separate from the mattress frame inclosed by said edge-plate, both plates having a corre- :sponding series-of hook holes for attaching the springs and the folded plate having flat clamping extensions gripping the fabric in-v side of the core-plate.

In witness whereof we have hereunto set our hands, before two subscribing Witnesses,l this first day of November 1912.`
